CHANNEL 1/4" PHONE JACK INPUT Sturdy one piece aluminum handles make for easy transporting along with facilitating rack installation. Four 10-32 x . 5" phillip machine screws are normally used to secure the amp. POWER SWITCH This stereo phone jack is designed to receive either balanced or unbalanced input signals. Balanced signals coming into this jack should be wired with the connector's tip going to signal + and the connector's ring to signal -. 9. SPEAKER OUTPUTS Check the power amp connections and verify the AC line power source before engaging the POWER switch. The yellow LED unmistakably indicates that all circuits are properly powered up. This color was chosen so the operator could see other red indicators from a distance. 3. CHANNEL LEVEL CONTROL The standard 1/4" SPEAKER jacks are used for most applications. SPEAKER BINDING POSTS A precision 41 step input LEVEL attenuate is used to adjust the volume levels. To deliver the amps full power without reducing headroom of the signal source, the level controls should be turned up approximately 1/3 (15 on the dial). 4. CHANNEL SIGNAL INDICATOR For heavy-duty speaker connections, use the rear BINDING POSTS to connect your speakers. Wire sizes up to 7 gauge (50 amps) can be inserted into the binding posts "side holes". Larger cable can be used with "banana" plugs which plug into the ends of the binding post (remove colored caps). Use the two center RED binding posts for BRIDGE speaker connections (see 11 BRIDGE MODE). 11. BRIDGE MODE--25V/70V DISTRIBUTION SYSTEMS The green SIGNAL LED indicators will start to flash when there is a signal passing to your speakers (-30dBM). This lets you know when the amp is passing a signal to your speakers. 5. CHANNEL CLIP INDICATOR The red CLIP LED indicators will start to flash when each channel has reached its maximum output. However, consistent flashing caused from higher frequencies may damage high frequency drivers (excessive distortion). EQ EXPAND SWITCH The HT150 can be operated in bridge mode if you require a 25V / 70V distribution speaker system or a high powered mono (single channel) amp. With your amp off, push in the rear BRIDGE switch after you have made your speaker connections to the rear center RED binding posts (ch 1 is + and ch 2 is -).
